Actually, I think I found the answer to the minimal amount of X libs necessary.
I got rid of --disable-glx from my build config and ran into the following when running configure: checking for XF86VIDMODE... no checking for DRIGL... no configure: error: Package requirements (x11 xext xdamage xfixes x11-xcb xcb-glx >= 1.8.1 xcb-dri2 >= 1.8) were not met: No package 'x11' found No package 'xext' found No package 'xdamage' found No package 'xfixes' found No package 'x11-xcb' found No package 'xcb-glx' found No package 'xcb-dri2' found Is there a way around needing all of these just to build libGL if I just want to run OpenGL with EGL and write to memory?
